Cosmetic container having release prevention device

Abstract

The cosmetic container having a release prevention device in which a vertical bar type stopper is applied to a release-prevention and locking device and a vertical panel type protrusion having teeth is installed to implement a stopper function, a release-prevention function, and a remaining liquid absorbing function. The cosmetic container includes a connector tube stuck to the inner wall of the cylinder, a hollow piston coupled with the lower end of the connector tube to support the connector tube, a release-preventing and locking device having a lower end to be inserted into the cylinder and allowing a screw-coupling of an upper outer side of the cosmetic container, and a push button coupled with the top of the release-preventing and locking device and pumping the hollow piston while up-and-down movements to pump the content in the cosmetic container out through an ejection hole.

What is claimed is: 
     
       1. A cosmetic container having a release-preventing device comprising:
 a cylinder formed with a pressure chamber where content in a cosmetic container is suctioned and temporally accommodated; 
 a connector tube stuck to the inner wall of the cylinder; 
 a hollow piston coupled with the lower end of the connector tube to support the connector tube; 
 a release-preventing and locking device having a lower end to be inserted into the cylinder and allowing a screw-coupling of an upper outer side of the cosmetic container; and 
 a push button coupled with a top of the release-preventing and locking device and pumping the hollow piston while up-and-down movements pump the content in the cosmetic container out through an ejection hole, having an inner guide body and an outer guide body parts coupled with the release-preventing and locking device, and a plurality of blades formed on the push button on the outer circumference of the inner guide body to determine up-and-down movements of the inner guide body; 
 wherein the release-preventing and locking device includes: 
 a first cylindrical guide unit allowing the inner guide body of the push button to slide; 
 a second cylindrical guide unit allowing the outer guide body of the push button to slide; 
 a semi-circular stopper inserted into the inner circumference of the first cylindrical guide unit to lock the blades and to block descending of the push button to prevent a liquid in the cosmetic container from being pumped out; 
 a push button movement space formed on the first cylindrical guide unit and allowing an up-and-down movements of the blades of the push button with the parts except for the semi-circular stopper such that pumping caused by the descending of the push button is enabled; and 
 a vertically lengthwise protrusion installed at the top side end of the stopper and having a vertical end of a left side and a sloped end of a right side to block a clockwise rotation of the push button and to allow a counterclockwise rotation of the push button. 
 
     
     
       2. The cosmetic container of  claim 1 , wherein the first cylindrical guide unit comprises a first bump protrusion installed at a side of the push button movement space and temporally blocking a horizontal rotation of the push button when the push button rotated to be positioned at a pumping position. 
     
     
       3. The cosmetic container of  claim 2 , wherein the first bump protrusion has both oblique sides. 
     
     
       4. The cosmetic container  claim 2 , wherein the first cylindrical guide unit comprises a second bump protrusion installed on the semi-circular stopper, positioned at a left side of the vertically lengthwise protrusion, and temporally blocking a horizontal rotation of the blades of the push button when the push button rotates clockwise and is positioned at a position where pumping is not carried out. 
     
     
       5. The cosmetic container of  claim 4 , wherein second bump protrusion has both oblique sides. 
     
     
       6. The cosmetic container of  claim 4 , wherein the second bump protrusion has a tooth shape with both swollen sides and a concave center such that the blades of the push button ride thereon and suctioning of the remaining liquid is enabled.
